Forget National Geographic, just study Justin Bieber.<br /><br />The singer debuted two more giant tattoos on his Instagram story… One of a bear on his chest and another of an eagle on his torso. He even showed them off while dancing with an elderly fan who seems pleased. <br /><br />Bieber is no stranger to tattoos, with more than 50 stretched across his body, and even a small cross on his face...<br /><br />Nature and religion are common themes for Bieber, including his "Son of God" tat across his stomach.<br /><br />And even though Us Magazine reports that Bieber calls the process "mad uncomfortable," he obviously has no plans to stop getting inked up.<br /><br />Now that he's as tatted up as he is, there's certainly no reason to be surprised if he gets another.<br />
